ATo4 aJZ whom, timmy conc-ern,.-

Beit known that I, JOHN H. KREssLER, a citizen of the United States, residing at Beth- State of Pennsylvania, have invented a new and useful Wheel-Tire, of which the4 follow- .loi

ing is a speciiication.

This invention relates to tires, and especially to that class of tires known as cushion-tires, 'and :has for its object to provide a tire embodying new and improved features oi' resiliency, durability, and reliability.

A further object of the invention is to provide a .cushion-tirecapable of responding to varying degrees of pressure and impact.

Al further object of the invention is to provide a core for use withinan outer casing by the use of which an outer casing-of the construction usually employed upon pneumatic tires may be convertedinto a cushion orspring tire.

A Jurther object ofthe invention is to provide a core for an outer tire-casing comprising a helical spring internally iiiling the casing, in which is another and smaller helical spring, and within that-again a third and smaller helical spring or a ring of rubber or other elastic material.

, With these and other objects inview the present invention consists in the combination and arrangement of parts, as will be hereinafter fully described, shown in the accompanying drawings, and particularly pointed out in the appended. claims, it being understood that changes in the form, proportion, size, and minor details may be made without g departing from the'spirit or sacriiicing any of its advantages.

In the drawings, Figure 1 isa View of thev tire in side elevation with portions broken away. Fig. 2 is a transverse sectional view of the improved-tire, taken on line 2 2 of Fig. l. Fig. 3 is a transverse sectional view of a Jform wherein the elastic -ring shown in Figs. l and 2 is replaced by an additional helical spring.

Like characters of reference indicate corresponding parts in all 'of the iigures of the drawings.

The improved tire forming the subjectmatter of this application comprises an outer casing of any approved and usual form and here shown as the clencher7 l10. Vithin the casing 10 is mounted a core comprising a spring 11, composed of a flat strip of spring material coiled in the form of a helix and to substantially fill the casing. l To provide forv inequalities in the diameter of the casing, la guard 12 is provided arranged to be compressed within the casing and by its expansion to hold the casingiirmly upon the spring. The guard 12 also serves to prevent the casing and spring from expanding over the rim to a4 degree suriicient to break the parts.

Within the helical spring 11 is mounted asecond spring 13, also coiled as a helix, but smaller than spring 11 and of' a reversewind, so that the coils of the two springs cross at each convolution. The spring 13 being' under tension is held in contact with the inner side of the spring 11 and transversely eccentric thereto. Within the spring 13 is mounted a ring 14, of rubber or other elastic material, which being also under tension is held in contact with the inner side of and eccentric to spring 13. Instead of the elastic ring 14 a heavy helical spring 15 may be substituted vand reinforced, if desired, by a guard 16, disin contact with the inner side of and eccentric to the spring 13 with the guard 16 clamped firmly therebetween.

It will be readily seen that a light or ordinary load will be supported upon the spring 11, which being of spring material is resilient, thus carrying the vehicle smoothly .and

evenly. With a heavy load the spring 11 is compressed until it comes into contact with the spring 13, when the vehicle is supported by the resiliency of both springs. Should the tire strike a curb or other obstruction, the springs 11 and 13 will be together compressed until they contact with ring 14 or inner spring 15, which will receive and .cushion the force of the impact,-thus saving from damage the wheel, vehicle, and occupants.

Having thus described the invention, what is claimed is 1. AV tire comprising a flexible casing, a yielding core a proximately iilling the casing IOO and a guard-p ate between the core and casing and arranged to stretch the casing tightly upon the core.

2. A tire comprising a 'flexible casing, a

the core and casing to stretch the casing tightly upon the core.

'4. A tire embodying a exible casing, a helical spring within and approximately ll ing the casing, a yielding ring within the spring and means between the ring and spring to support the ring under impact.

5. A tire embodying a flexible casing, a helical spring within and approximately filling the casing, a yielding ring disposed eccentrically within the spring and a segmental supporting-plate between and eccentric to n the ring and spring.

6. A tire embodying a flexible casing, a helical spring within and approximately filling the casing, means between the spring and casing to stretch the casing tightly upon the spring, a yielding ring within and concentric to the spring and a segmental 'supporting-I plate between and eccentric to the ring and spring. l 7. A tire embodying a flexible casing, ya, helical spring within and approximately iillrV ing the casing, a segmental plate 4between the spring and casing and arranged 'to support t e spring under compression, a yielding ring Within and'concentric to the spring and a segmental supporting-plate between and eccentric to the ring and spring.

8. A tire embodying a flexible casing, a helical spring within the casing, a helical spring of smaller diameter and reverse Wind within and eccentric to the outer spring; a yieldable core .eccentrically within the inner spring, and a segmental supporting-plate between and eccentric to the ring and spring.

9. In a tire a casing,`a removable inner core comprising a helical s ring substantially filling the easing, a helical spring of smaller transverse diameter and reverse wind mounted eccentricallyrv within the uterspring, an elastic ring mounted eccentrically within the inner spring, a guard-plate mounted be- WGGII the outer spring and the casing and arranged to stretch the casing tightly upon the core, and the spring, guard and ring contacting at their inner side.

In testimony that I claim the foregoing as y own I have hereto afiixed my signature in the presence of two witnesses.
